So after purging filthy xeno in Stellaris I have returned to have look at this mod in lieu of making unit changes proposed by me.
1). Naval units changes should be based on different unit types not long list of modifiers that look extremely bad from aesthetics PoV. What I mean that naval units as category is replaced by four unit types. On land you have melee, archery, cavalry (light and heavy) etc. Idea is the same escort, capital, transport and raiders are separate unit types. In this way you can replace current unwieldy vs. individual unit bonuses with simpler much more clean vs. unit type ones.
2). Heavy galley still has +25% coast attack, it should be removed because it makes it to good vs. galleass.
3). Destroyer should be available at ballistics but escort destroyer should still be buildable with electronics. Currently both are at same tech.
4). Heavy cavalry should not have city defence penalty, they can't fortify and are more expensive. That's enough penalty.
5). Cuirassier shouldn't have penalty vs pike. Pike is 9

vs cuirasser 8

after pike bonus, it's also cheaper. Penalty was proposed when I was toying with various

, ultimately decided it wasn't necessary.
6). Cavalry shouldn't have open terrain bonus.
7). Super-carrier should have one more cargo slot for fighter so it's better than normal carrier.
8). For aesthetic reasons trim cavalry(unit type) vs. siege units list and standardise it. Either light or heavy horse should have flanking bonus vs siege.
For example: Chariot vs catapult. Horse archer vs catapult and trebuchet. Pistolier vs bombard, cannon. hussar vs cannon, artillery. Cavalry vs artillery, howitzer. Then remove horseman bonus and flanking vs siege. Lancer loses flanking vs catapult and trebuchet.
